Методика

The same operation as in Example (77d) was performed using ethyl cis(±)-2-(3-amino-4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}piperidin-1-yl)-1,3-benzothiazole-7-carboxylate obtained by the method described in Example (81e) (30 mg, 0.063 mmol), tetrahydro-4H-pyran-4-one (0.11 mL, 1.19 mmol) and sodium (triacetoxy)borohydride (238 mg, 1.12 mmol), to obtain 19.1 mg of the title compound as a white solid (54%).
